Scour downstream of a block ramp in asymmetric stilling basins [PDF]

, 2008
Block ramps are hydraulic structures generally used in mountains rivers. In the last decades they have become more common in river restoration as they minimize the environmental impact.

The Legacies of Lockdown: Moral Logics of Exchange and Mistrust in Postpandemic China

Economic Anthropology, EarlyView.
ABSTRACT When Shanghai entered an extended lockdown under China's Zero‐COVID policy in spring 2022, residents found themselves confined within their residential compounds, cut off from conventional supply chains, and dependent on improvised systems of local provisioning and state rationing. From the perspective of economic anthropology, such conditions

Physical modeling of local scour development around a large-diameter monopile in combined waves and current [PDF]

, 2014
In most of the previous studies on local scour around pile foundations, wave-induced pore pressure response has not been taken into account. The local-scour and pore-pressure responses around a large-diameter monopile in combined waves and current have ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

Journal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...

SCOUR NEAR SPILL-THROUGH TYPE ABUTMENT ON CLEAR-WATER SCOUR CONDITION FOR MULTI-SECTION CHANNELS

Journal of Civil Engineering
Scour is a natural phenomenon caused by erosion due to water flow on the alluvial channel bed and channel wall. In fact, scour happened in the bridge abutment is total scour, that is a combination between local scour, general scour, and constriction ...

Structural defence for plunge pool scour [PDF]

, 2006
Plunge pool scour is a major topic in presence of hydraulic structures that foresees the production of jets. The scour hole is a function of several variables including the tailwater, the densimetric Froude number, the sediment granulometry, the water ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

Integrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

Does an Armor Layer Control Clear-Water Scour at Cylindrical Bridge Piers? A Comprehensive Experimental Assessment under Steady and Unsteady Flow Conditions

Journal of Hydrology and Hydromechanics
Local scour at bridge piers is a critical phenomenon jeopardizing structural integrity worldwide. This study presents a comprehensive physical modelling investigation into the evolution of local scour in the presence of a protective armor layer ...
